A decentralized power system for telecommunications equipment

Abstract

Nippon Telegraph and Telephone Corporation has been introducing a decentralized power supply which incorporates advanced technological characteristics in the system configuration. These characteristics include load voltage regulation, DC backup circuits, supervision and control using microprocessors, and organization of the power equipment into modularized units that are compact and lightweight. This power system is effective for reducing the scale of communications problems which occur due to power equipment failure and can flexibly adapt to communications facility scale.<>
